All the Numbers to Measure a Runner

Once running gets serious, fēnix 3 Sapphire HR with optional HRM-Run monitor tracks all the advanced metrics that are needed to better understand and improve:

Advanced Running Dynamics analyse your running:

Vertical oscillation and ratio — the degree of ‘bounce’ in your running motion and the benefit ration to stride length

Ground contact time and balance — shows how much time, in the running motion, your foot is on the ground rather than in flight and lets you check your running symmetry

Lactate threshold – Through analysis of your pace and heart rate, fēnix 3 estimates the point where your muscles start to rapidly fatigue

You know your way

fēnix 3 Sapphire HR provides comprehensive navigation and tracking functionalities to guide you on and off the beaten track. fēnix 3 records a GPS track log creating a “bread crumb trail” as you move. It also allows you to mark locations, such as a start/finish line, course checkpoint, or a campsite, vehicle or other point of interest. With fēnix 3, you can create and follow courses or mark up to 1,000 locations and navigate to them. Plan trips and share adventures with friends and family using BaseCamp™ – Garmin’s free planning tool on your computer.

More than just ABC sensors

fēnix 3 Sapphire HR is equipped with a barometric altimeter and an electronic 3-axis compass. The device auto-calibrates these sensors using its GPS receiver to provide the most accurate information possible. The built-in altimeter provides elevation data to accurately monitor ascent and descent, while the barometer can be used to predict weather changes by showing short-term trends in air pressure. The 3-axis electronic compass keeps your bearing whether you’re moving or not. For accurate temperature reading from the watch, pair the fēnix 3 with our external tempe temperature sensor.
